IMPROVEMENT IN GOVERNORS FOR STEAM-ENGINES.

Specification forming part of Letters Patent No. 144,204, dated Ncvcmber4, 18723; application filed August 1S, 1873.

To all whom Ait may concern:

Be it known that I, JOHN E. HUGOU, of Richmond, county of Wayne, Stateof Indiana, have invented certain Improvements in Governors forSteam-Engines, of which the following is a specication:

My invention relates to an improvement in governors for steam-engines,wherein I use a cylindrical valve-seat, placed in a chamber, saidvalve-seat being perforated, and having a cylindrical valve, alsoperforated to correspond, as hereinafter described.

Figure l is a vertical section, showing the valve-seat E placed incasing A 5 also, the valve H in position. Fig. 2 is a cross-section.Fig. 3 is a view of the valve seat E. Fig. 4 shows the upper portion ofthe valve-stem P as constructed. Fig. 5 is a view of the valve H,showing the slot X. Y

A is the casing, into which the valve-seat E is placed. Bis thesteam-chamber in the casing A and around the seat E, as shown in Figs.land 2. D, Fig. 1, is the packing, which forms a steam-joint between thecasing A and seat E. The holes Lin the seat E correspond with the holesM in the valve H. The lower end of the valve stem P is threaded, and

passes through the cross-head N, which crosshead is suspended on pivotsin the upper end of the valve H, by which arrangement the valve may beadjusted, as required, by turning the stem to give the required change.The slot X, Fig. 5, in the valve H, passes over the pin I in thevalve-seat E.

The steam is admitted into the chamber B through the port F, and passesaround the seat E and through the holes L in the same, and through theholes M in the valve, the amount of steam admitted through the holes Lin the seat and M in the valve being governed by the adjustment of thevalve up or down, as required.

Having thus fully described my invention, what I claim, and desire tosecure by Letters Patent, is

The combination of the cylindrical valve H, having the slot X,cross-head N, and threaded valve-stem F, with the cylindrical seat E,provided with pin I, and chamber B, all constructed substantially as andfor the purpose set forth.
